I got a sore throat that promised a full-out fever + asthma attack, so I went to the doctor for some pre-emptive meds, and curiously noticed:

Flu meds = sleep inducers; duh, everyone knows that;

Asthma meds = steroids; I know this, I used to take 'em all the time;

So the final effect is my heart racing like a horse while my body collapses into sleep. It's not as trippy as the time I took flu meds with coffee, but interesting all the same.
